Production Method and Filter Comprising Non Woven Fabric and/or Filtering Injector Structures or Sheets Which are Obtained Using Said Method and Which are Intended for the Filtration and Which are Intended for the Filtration and Elimination of Legionella Pneumofila in any Installation at Risk From Legionella Pneumofila Proliferation

Abstract

The invention relates specifically to the physical and chemical characteristics of an air and liquid filter which is intended to trap bacteria and eliminate same. The inventive fabric is manufactured from a fabric comprising non woven type fabrics and / or injected filtering structures or sheets, i.e. which have been obtained by manipulating synthetic artificial fibres using processes that lead to the formation of a lap which, following other industrial operations that are described later, is converted into the non woven fabric or, alternatively, using injection processes into the injected structures or sheets.

[0001] The invention relates specifically to the physical and chemical characteristics of an air and liquid filter which is intended to trap bacteria and eliminate same. The inventive fabric is manufactured from a fabric comprising non woven type fabrics and / or injected filtering structures or sheets, i.e. which have been obtained by manipulating synthetic artificial fibres using processes that lead to the formation of a lap which, following other industrial operations that are described later, is converted into the non woven fabric or, alternatively, using injection processes into the injected structures or sheets. [0002] Another objective is the characteristics of the fibres in the aforementioned non-woven fabric, as well as the treatment that they include, which seek to fix the necessary chemical compounds directly onto the fibres.

Benefits of technology

[0002] Another objective is the characteristics of the fibres in the aforementioned non-woven fabric, as well as the treatment that they include, which seek to fix the necessary chemical compounds directly onto the fibres. This allows the non woven fabric, once manufactured, to act as a filter which is able to prevent Legionella continuing to circulate through the inside of cooling towers, heat exchangers, ventilation machines, tanks or any device listed previously and reaching concentrations which are dangerous to man.

Problems solved by technology

In order to do this authorised disinfectants have to be used, for example hyperchlorination of towers is effective, but this only has a short term effect and the problem usually reoccurs within a month, sometimes days of the disinfection.

Also, hyperchlorination is not effective in pipes or conduits as well as in other heated areas in the installation.
